Industry wide, QC is so abhorrent that brand discussion isn't worth much. They all turn out crap on a regular basis. Factory and dealer support is generally lacking as well. It's not too easy as a consumer to spot problems on the dealer lot. It's a roll of the dice. If any industry suffers worse QC across the board, I am not aware of it. RV industry QC makes Ruger QC look like a gold standard.
